I agree with Wda, the Brown Electronic Lab BEL MArk V 1001. I'd like to bi-amp my magneplanars 3.6's. I have auditioned them, the BELs, but only for a day. They pull more out of the music than most power amps. The best presence and soundstage in a SS amp I've heard. Yet, I am tube bound, but the BELs have my interest, my sincere interest. $4000 for each. If you can, give them a try. Unfortunately no web site.
